When your bananas are on the turn (the blacker the better) pop them whole into the freezer without peeling. Defrost (in a bowl - they leak!) and snip off one end. You can then squeeze out your blob of banana mush, to be used in banana loaves, biscuits, muffins etc. with minimal mashing. It's true that bananas don't freeze at all well for raw consumption but they freeze like a dream for cake making.
